There does not exist a project template that uses Typescript with Express4, there does however exist typescript template using express3. Is it that TS is incompatible with Express4.

I tried by creating regular TS with Express3 template, uninstalled Express3 npm package and added Express4 package. It did not compile.
I also added TDS as explained in https://code.visualstudio.com/Docs/runtimes/nodejs and it gave more errors like cannot find property express.favicon().
